Is it true that a snake can lay fertile eggs even when it has never been with a male?

Supposedly a Burm laid fertile eggs without being with a male, last year. That is the only case I have heard of, but female pythons have laid infertile eggs, because they were close to a male (pherimones suspected). That is partially the reason we bred Elvira, so she wouldn't lay a dud clutch or get egg bound with infetile eggs (harder on the snake than becoming fully gravid). Vern's 2 females laid infertile eggs this year, without being with the males, but they were close to the males.
